Determine the fault current in the system following a double line to ground short circuit fault at the terminal of a star connected synchronous generator operating initially on an open circuit voltage of 1.0 pu. The positive, negative, and zero sequences reactance of the generator are, respectively j0.35, j0.25, and j0.20, and the star point is isolated from the ground.
